HUMIDIFIER,

Application filed. March as, 1930. Serial No. 439,760.-

densation within the steam diffusing pipe by arranging said pipe tolie,- throughout all or a major portion of its length, in closeproximity to the live steam pipeto which it is connectecl. v

A further object is to provide the steam diffusing pipe with steamdischarge openings arranged opposite and close to the live steam pipe,so that the impingement of the escaping steam upon the heated surfaceofthe live steam pipe further retards the formation of condensate.

A still further object is to provide novel means for causing evaporationof the con densate formed within the steam diflusing pipe. 4 i

Other purposes, advantages and characteristic features of the inventionwill be more readily understood from the following de tailed descriptionand accompanying drawings, wherein Figure 1 is a perspective view of aradiator and live steam pipe assembly equipped with my invention. 7

Figure 2 is an enlarged fragmentary detailed view of the live steam.supply pipe showing clearly the manner in which my invention isassociated therewith.

"' section, of a slight modification.

Referring more particularly to the drawings, l1 designates a radiatorequipped with a live steam supply pipe indicated at 12. Pipe 12 may beprovided with any suitable form of valve 13 for controlling admission ofAnother object is to reduce steam con-' Figure 3 is a view, principallyin vertical i any cooling present invention, I provide a valve casing 14steam to the radiator 11. According'tothe which is connected to the pipe12 between the V valve 18 and the source of steam- Valve casing 1 1i maybe equipped with any suitable type of valve 15 for controllingtheflow'of steam from the pipe 12 to the steam difiusing pipe 16. Diiiusingpipe 16 is formed to present a vertical portion 16a lying in closeproximity to the live steam pipe 12 and an offset upper portion 16?)connected to the bottom of the valve casing 14. The vertical portion 16dof the diffusing pipe 16*is formed with a plurality of relatively smallopenings 16o positioned close to and directly opposite the live steampipe 12. At its lower end, the vertical portion16a of the diiiusing pipeis provided with arelatively small opening 16d forthe escape ofcondensate. Y

When the valve 15 is opened, steam flows from the live steam supply pipe12 through the valve casing 14 into thesteam diffusing pipe 16. Thesteam escaping fromthe pipe 16 through the openingslficimpinges direct-1y upon the adjacent heated surface of, the live steam pipe 12, so thatcondensation is reduced to a minimum. Condensation of the steam withinthe difi'using pipe 16 isalso, re-

tardedv by the arrangement of this pipe to extendinclose parallelrelation with respect to the heated live steam supply pipe 12. The smallamount of condensate forming within the diffusing pipe 16 fio ws.downwardly through openings 16d onto a suitable absorbing material 17which may consist ofblotting paper wrapped around thelive steam pipe 12andjh'eid in place by suitable split clamps 17 a. 'ofwell-knownconstruction. By reason of. its contact with the pipe 12, the absorbentmaterial 17 i is maintained at a sufficiently high temperature to elfeotrapid evaporation of the condensate delivered thereto- The thickness ofthe absorbent'material 17 should be. relatively slight sothatfthe.entire body oi: the absorbent material may be maintained at atemperature sufliciently high to prevent of the 1 condensate deliveredthereto. 5 In Figure 3, I have shown a desirable modification, whereinthe steam diffusing openings.

1.9 are confined to the lower portion of the diffusing pipe 20 and arecovered by the upper portion of the absorbent material 21 to which thecondensate is delivered.

In the foregoing I have disclosed several Ways in which the steamdelivered to the steam diffusing pipe is permitted to escape into theatmosphere. It will be understood, however, that this feature of theinvention may be varied to provide for escape of the steam into theatmosphere in any sutiable manner, although, in certain installations,it will be found preferable to have the escaping steam directed againstthe heated steam supply pipe, as shown in Fig. 1, as this materiallyreduces condensing of the escaping steam; In both forms of theinvention, as herein disclosed, it Will be noted that the condensateformed within the steam diffusing -3 pipe is delivered to a highlyheated body of absorbent material so that rapid evaporation 'of thecondensate is provided for in such manner as to avoid objectionabledrippage. --This' delivery of the condensateto an absorbent body ofmaterial heated by the live steam pipe is a very important feature ofthe invention. It provides for rapid evaporation of the condensate andpractically eliminates drippage.

I claim:

1. The combination with a vertically extending live steam pipe, of avertically eX tending steam diffusing pipe having its upper endconnected to said live steam pipe, said at diffusing pipe being providedwith a plurality of openings for the escape of steam and with a bottomopening for the escape of condensate, and a body-of absorbent materialsi'irroui'iding the live steam pipe and posi- 40 tione'd to receive thecondensate formed Within the diffusing pipe.

2. The combination with a live steam pipe of a diffuser connectedthereto and functioning to diffuse steam into the atmosphere, saiddiffuser having an opening in the lower portion thereof for the escapeof condensate and a body of absorbent material surrounding the livesteam pipe and positioned to receive the condensate escaping throughsaid opening. 3. The c'on'ibination with a vertically extending livesteam pipe of a vertically disposed difi'user connected thereto andfunctioning to diffuse steam into the atmosphere, said diffuser havingan opening at its lower end for the escape of condensate and a body ofabsorbent material covering said opening and surrounding the live steampipe, the arnngement being such that the absorbent material is heated bythe live steam pipe so that the condensate absorbed by said material ievaporated into the atmosphere.

In Witness whereof, I have hereunto set my hand. I
